# nibbleArray
Arduino library for a compact array of nibbles (4 bit units)
## Description
A nibble is a 4 bit element, which can hold a value 0..15 (0..F in HEX).
The nibbleArray is an array that stores 2 nibbles in a byte therefor it is
twice as small as a normal array.
The current implementation can hold 510 elements. This is due a limitation of
the UNO which can alloc max 255 bytes in one **malloc()** call.
This **NIBBLEARRAY_MAXSIZE** can be defined compiletime "-D NIBBLEARRAY_MAXSIZE"
or one can adjust it in the library if other platforms can allocate more memory.
## Interface
The interface of the nibbleArray is straightforward:
* **get(index)** idem
* **set(index, value)** idem
* **clear()** set all elements to 0;
* **SetAll(value)** set all elements to value
## Operation

# PCA9635
Arduino library for PCA9635 I2C 8 bit PWM LED driver
# Description
This library is to control the I2C PCA9635 PWM extender.
The 16 channels are independently configurable is steps of 1/256.
this allows for better than 1% finetuning of the duty-cycle
of the PWM signal.
### interface
**begin()** initializes the library after startup. Mandatory.
**begin(sda, scl)** idem, ESP32 ESP8266 only. Library does not support
multiple Wire instances (yet).
**reset()** resets the library to start up conditions.
----
**setLedDriverMode(channel, mode)** mode is 0..3 See datasheet for full details.
| LED mode | Value | Description |
|:----|:----:|:----|
| PCA9635_LEDOFF | 0x00 | led is 100% off, default @startup
| PCA9635_LEDON | 0x01 | led is 100% on.
| PCA9635_LEDPWM | 0x02 | set LED in PWM mode, 0..255
| PCA9635_LEDGRPPWM | 0x03 | add LED to the GRPPWM*
\* all leds in the group GRPPWM can be set to the same PWM value in one set.
This is ideal to trigger e.g. multiple LEDS (servo's) at same time.
**getLedDriverMode(channel)** returns the current mode of the channel.
----
**write1(channel, value)** writes a single 8 bit PWM value.
**write3(channel, R, G, B)** writes three consecutive PWM registers.
**writeN(channel, array, count)** write count consecutive PWM registers.
May return **PCA9635_ERR_WRITE** if array has too many elements
(including channel as offset)
**writeMode(reg, mode)** configuration of one of the two configuration registers.
check datasheet for details.
**readMode(reg)** reads back the configured mode, useful to add or remove a
single flag (bit masking)
----
**setGroupPWM(uint8_t value)** sets all channels that are part of the PWM group to value.
**getGroupPWM()** get the current PWM setting of the group.
**setGroupFREQ(value)** see datasheet for details.
**getGroupFREQ()** returns the freq of the PWM group.
**lastError()** returns **PCA9635_OK** if all is OK, and other error codes otherwise.
| Error code | Value | Description |
|:----|:----:|:----|
| PCA9635_OK | 0x00 | Everything went well
| PCA9635_ERROR | 0xFF | Generic error
| PCA9635_ERR_WRITE | 0xFE | Tries to write more elements than PWM channels
| PCA9635_ERR_CHAN | 0xFD | Channel out of range
| PCA9635_ERR_MODE | 0xFC | Invalid mode
| PCA9635_ERR_REG | 0xFB | Invalid register
| PCA9635_ERR_I2C | 0xFA | PCA9635 I2C communication error
# Operation

# PCA9685_RT
Arduino library for I2C PCA9685 16 channel PWM extender
# Description
This library is to control the I2C PCA9685 PWM extender.
The 16 channels are independently configurable in steps of 1/4096.
This allows for better than 0.1% finetuning of the duty-cycle
of the PWM signal.
The PWM's of the different channels have individual start and stop moments.
This can be used to distribute the power more evenly over multiple servo's
or give special effects when used in an RGB LED.
The frequency of the PWM can be set from 24 to 1526 according to the datasheet, however in practice not all frequencies are set accurate.
Lower frequencies do better than higher frequencies.
### interface
**begin()** initializes the library after startup. Mandatory.
**begin(sda, scl)** idem, ESP32 ESP8266 only. Library does not support
multiple Wire instances (yet).
**reset()** resets the library to start up conditions.
**writeMode(reg, mode)** configuration of one of the two configuration registers.
check datasheet for details.
**readMode(reg)** reads back the configured mode, useful to add or remove a
single flag (bit masking)
**setPWM(channel, ontime, offtime)** The chip has 16 channels to do PWM.
The signal is divided in 4096 steps, 0..4095.
The pulse can begin =**ontime** on any step and it can stop on any step =**offtime**.
This allows e.g. to distribute the power over the 16 channels, e.g. the
channels do not need to start at the same moment with HIGH.
**setPWM(channel, offtime)** simple PWM that always start on **ontime = 0**
**getPWM(channel, ontime, offtime)** read back the configuration of the channel.
**setFrequency(freq, int offset = 0)** set the update speed of the channels.
This value is set the same for all channels at once.
The frequency is constrained to be between 24 and 1526 Hz.
As the frequency is converted to an 8 bit **prescaler**,
the frequency set will seldom be exact.
After changing the frequency, one must set all channels (again),
so one should set the frequency in **setup()**
The parameter offset can be used to tune the **prescaler** to get a frequency
closer to the requested value. See **PCA9685_setFrequency_offset** example.
Default the offset = 0. As the prescaler is smaller at higher frequencies
higher frequencies are less accurate.
Making offset too large can result in very incorrect frequencies.
When using offset, the **getFrequency(false)** will return the adjusted prescaler.
**getFrequency(cache = true)** get the current update frequency of the channels.
This is same for all channels. If cache is false, the frequency is fetched and
calculated from the **prescaler** register and will probably differ from the
value set with **setFrequency()**.
**digitalWrite(channel, mode)** mode = HIGH or LOW, just use the PCA9685 as
a digitalpin.
This single function replaces the setON() and setOFF() that will become
obsolete in the future.
**allOFF()** switches all PWM channels OFF. **Experimental** in 0.3.0
To "undo" the allOFF one can call the **reset()** function and set all
PWM channels again.
**lastError()** returns **PCA9685_OK = 0** if all is OK, and
| Error code | Value | Description |
|:----|:----:|:----|
| PCA9685_OK | 0x00 | Everything went well
| PCA9685_ERROR | 0xFF | generic error
| PCA9685_ERR_CHANNEL | 0xFE | Channel out of range
| PCA9685_ERR_MODE | 0xFD | Invalid mode register chosen |
| PCA9685_ERR_I2C | 0xFC | PCA9685 I2C communication error

# PAR27979
This is just a collection of simple macros,
not a real class with a stream as param
(todo someday somewhere)
Arduino library for the Parallax 27979 serial display
## Description
The library is essentially a wrapper around a Stream, typically Serial,
Serial2 (3,4..) or newSoftSerial or equivalent.
This stream is given as parameter in the constructor.
The library implements the **Print** interface to print integers
floats and strings and all printable types.
The library does not keep any state information, it only implements a few
methods to make working with it easier.
These methods are quite trivial.
* **on()** switch display on
* **off()** switch display off
* **clearHome()** clear the display
* **backlightOn()** enable the backlight
* **backLightOff()** disable the backlight
**Movement**
* **cursorLeft()** move cursor
* **cursorRight()** move cursor
* **lineFeed()** idem
* **formFeed()** idem
* **gotoXY(x, y)**
**Sound support**
* **octave(octave)** octave = 3 4 5 6 7
* **duration(duration)** duration = 1 2 4 8 16 32 64
* **play(note)** note = 0 1 2 3 4 5 6 7 8 9 10 11 0=A 1=A# etc
* **noSound()**
## Support Parallax 27976 & 27977
Although not tested, the functions should work with the
Parallax 27976 and 27977 displays too.
## Operation
See example

# PrintCharArray
Arduino library to print to a char array
# Description
PrintCharArray is a class that buffers a number of print statements in a char array.
This char array can be processed later.
Typical usecase:
- buffer slow generated of a packet of data
and send it with minimum time between bytes
- print to buffer an see how long output is;
- buffer slowly generated data, and send it with minimum time between bytes
- print to buffer to see how many chars the output is;
use to prevent "display line overflow"
(e.g. floats)
## Operation

# PrintSize
Arduino library to determine the length of print statements
# Description
PrintSize is a minimal library to determine the length of a variable when printed.
This includes printing of floats
This includes printing of floats, integers in decimal or hex notation.
## Examples
Example show the alignment of 10 random numbers,
both print(), println() and if supported printf().
Works for **print()**, **println()** and if supported **printf()** e.g. ESP32.
Finally since **0.2.0** it has a total counter to add up the characters "printed" since
the last **reset()** call. (see example)
# Operational
Example shows the right alignment of 10 random numbers
Example shows (elementary) line fitting
### notes
Can be used to calculate the needed space.
- to properly do a right alignment e.g. for numbers.
- do left alignement and overwrite previous output with spaces.
- to properly do a right alignment e.g. for numbers or variable text
- do left alignement and overwrite previous output with just enough spaces.
- centering of numbers
- see if output will fit into a line.
- see if output will fit into a line / display

# PrintString
Arduino library to print to a String
# Description
PrintString is a class that buffers a number of print statements in a String.
This String can be requested to process later.
- buffer slowly generated data, and send it with minimum time between bytes
e.g. to maximize packets for ethernet
- print to buffer to see how many chars the output is;
use to prevent "display line overflow"
(e.g. floats)

# PulsePattern
Arduino Library to generate repeating pulse patterns **AVR ONLY**
## Description
This is an **experimental** library to generate pulse patterns by means of an Arduino UNO.
As the library uses **AVR hardware timers** it is definitely **NOT** working for ESP
or other non-AVR processors.
The library uses timer1 for the timing of the pulses.
Therefor the class is implemented with a static instance called PPO.
Still by calling init() one can change all parameters of the process.
One should note that calling init() forces the timer to stop.
The timer code is based upon the website of Nick Gammon which
holds quite a lot of good solid material (Thanks Nick!).
https://gammon.com.au/forum/bbshowpost.php?bbtopic_id=123
Use with care.
## Interface
- **PulsePattern()** constructor
- **init(pin, \*ar, size, level, prescaler)** initializer of the Timer1
* pin that outputs the pattern
* array of durations
* size (or part) of the array to be used
* starting level HIGH/LOW
* prescaler, one of the 5 defines from .h file (table below)
- **setFactor(perc)** percentage = factor to correct timing (relative).
- **getFactor()** get the internal used factor. Due to rounding it can be slightly different.
- **stop()** stop the pattern generator
- **start()** start the pattern generator
- **cont()** continue the pattern generator from the last stopped place (approx).
- **isRunning()** status indicator
- **worker()** must be public otherwise the ISR cannot call it.
There is some bad understood __vector_11() error when worker() is private.
### Prescaler constants
| Value | Prescaler | Timer1 | notes |
|:----:|:----|:----|:----:|
| 0 | NO_CLOCK | timer off | |
| 1 | PRESCALE_1 | clk / 1 | |
| 2 | PRESCALE_8 | clk / 8 | |
| 3 | PRESCALE_64 | clk / 64 | |
| 4 | PRESCALE_256 | clk / 250 | |
| 5 | PRESCALE_1024 | clk / 1024 | about 1 ms / pulse |
| 6 | EXT_T1_FALLING | T1 = pin 5 | not tested |
| 7 | EXT_T2_RISING | | not tested |
